That's strange to me. And am I correct that there is only one memory slot open or are there two slots open?

It only has only one slot but also has some memory (256MB) soldered directly on the logic board. The current powerbooks have an additional 256MB SODIMM in ths single slot so if you want more memory than that you need to remove the installed 256MB first. If you replace the SODIMM with a 1GB SODIMM you get a total of 1.25GB.

^^Yeppers, caveman is right. The 12" Powerbook comes with 512MB of RAM, but not a single 512MB stick of RAM. It comes with one 256MB stick of RAM that's soldered on, and a 256MB stick of RAM that you can take out and replace with a bigger stick.

The minimum amount of RAM a 12" PB can have now is 256MB of RAM, but it comes with 512MB. The max amount of RAM you can have in it is 256MB, although if a 2GB, 200-pin SODIMM stick of RAM came out, it might be able to work on a 12" PB.

Well, I use to have the 12" powerbook, and had to get rid of it for a fifteen because I got super tired of squinting at the type when it was late and my eyes were tired. Was a grad student at the time....common problem

yes, the 12" iBook and 12" PowerBook have the exact same size screens. they may appear to be slightly different sizes because of the smaller bezel around the powerbook screen. the iBook screen is surrounded by about an inch of plastic. whether or not they are the same make i do not know. i can say that my 12" PowerBook looks quite nicer than the 12" iBooks i see on a daily basis at client offices. but who knows really, maybe Apple actually calibrates the PowerBook display settings by default so they look nicer out of the box. i know a factory default screen setup on an iBook is just awful. all washed out and barely visible. i love the 12" PB and would never want anything larger in a portable. i do wish Apple didn't treat it as a second class citizen though. the last update pretty much ignored the 12" and the RAM limitation is lame.
